iview 兼容ie（部分功能）
郑重警告：我的代码在ie9下没有生效,只是在360的ie仿真模式下可以了（很疑惑，不是说是一个内核吗）
吐槽下：iview号称适配ie9，大爷的他们官网在ie9下都错乱了
1安装依赖
npm install babel-polyfill --save
2 在mian.js最前面添加
import 'babel-polyfill'
3在main.js中添加下面的代码
if (window.HTMLElement) {
if (Object.getOwnPropertyNames(HTMLElement.prototype).indexOf('dataset') === -1) {
Object.defineProperty(HTMLElement.prototype, 'dataset', {
get: function () {
var attributes = this.attributes; // 获取节点的所有属性
var name = [];
var value = []; // 定义两个数组保存属性名和属性值
var obj = {}; // 定义一个空对象
for (var i = 0; i < attributes.length; i++) { // 遍历节点的所有属性
if (attributes[i].nodeName.slice(0, 5) === 'data-') { // 如果属性名的前面5个字符符合"data-"
// 取出属性名的"data-"的后面的字符串放入name数组中
name.push(attributes[i].nodeName.slice(5));
// 取出对应的属性值放入value数组中
value.push(attributes[i].nodeValue);
}
}
for (var j = 0; j < name.length; j++) { // 遍历name和value数组
obj[name[j]] = value[j]; // 将属性名和属性值保存到obj中
}
return obj; // 返回对象
},
});
}
}

(function () {
var lastTime = 0;
var vendors = ['ms', 'moz', 'webkit', 'o'];
for (var x = 0; x < vendors.length && !window.requestAnimationFrame; ++x) {
window.requestAnimationFrame = window[vendors[x] + 'RequestAnimationFrame'];
window.cancelAnimationFrame = window[vendors[x] + 'CancelAnimationFrame'] ||
window[vendors[x] + 'CancelRequestAnimationFrame'];
}
if (!window.requestAnimationFrame) {
window.requestAnimationFrame = function (callback, element) {
var currTime = new Date().getTime();
var timeToCall = Math.max(0, 16 - (currTime - lastTime));
var id = window.setTimeout(function () { callback(currTime + timeToCall); },
timeToCall);
lastTime = currTime + timeToCall;
return id;
};
}
if (!window.cancelAnimationFrame) {
window.cancelAnimationFrame = function (id) {
clearTimeout(id);
};
}
}());
//remove报错处理
if (!('classList' in document.documentElement)) {
Object.defineProperty(HTMLElement.prototype, 'classList', {
get: function () {
var self = this;
function update (fn) {
return function (value) {
var classes = self.className.split(/\s+/g);
var index = classes.indexOf(value);
fn(classes, index, value);
self.className = classes.join(' ');
};
}
return {
add: update(function (classes, index, value) {
if (!~index) classes.push(value);
}),
remove: update(function (classes, index) {
if (~index) classes.splice(index, 1);
}),
toggle: update(function (classes, index, value) {
if (~index) { classes.splice(index, 1); } else { classes.push(value); }
}),
contains: function (value) {
return !!~self.className.split(/\s+/g).indexOf(value);
},
item: function (i) {
return self.className.split(/\s+/g)[i] || null;
},
};
},
});
}
4.调整下布局的属性基本就可以了
